Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water platform construction, in particular to a water module water balance pontoon and a water closing balance method. BACKGROUND

[0002] With the development of ocean engineering to the deep sea, floating wind power has become a key technology for developing deep-sea wind energy resources. Among them, the semi-submersible foundation is favored because of its relatively mature technology. In order to reduce the dependence on large docks and lifting equipment, and reduce the expensive time and risk of offshore operations, the water closing technology has emerged. This technology divides large semi-submersible platforms into several modules for construction on shore, and then transports them to the designated location at sea for overall docking.

[0003] However, a basic prerequisite for the successful implementation of existing water closing technology is that each module can completely float horizontally on the water surface. Each module is usually regular in shape, uniform in mass distribution, and can accurately adjust the draft and attitude by relying on the ballast system of the module itself, thereby achieving horizontal floating.

[0004] For some specific floating structures, such as the four-column semi-submersible platform used in some floating wind power projects, the split sub-modules belong to irregularly shaped and unevenly distributed modules. Especially when some small modules are unloaded into the water, due to the irregular shape and off-center gravity, they will immediately tilt or become unstable in posture, and cannot maintain the required horizontal state. This fundamental problem leads to the inability to perform subsequent precise wet towing and closing docking, which seriously restricts the application of modular water closing technology on irregular, non-ballast system platforms. In the existing technology, it is usually necessary to rely on large lifting equipment or modify the module to increase a permanent ballast system, which will greatly increase the cost and operational complexity. SUMMARY

[0005] Therefore, a water module water balance pontoon and a water closing balance method are provided to solve the problem that irregular water modules cannot maintain horizontal floating by themselves.

[0006] Embodiments of the first aspect of the present application provide a water module water balance pontoon, comprising:

[0007] a bearing frame for connecting with a water module;

[0008] a buoyancy mechanism for providing additional buoyancy, disposed on the bearing frame;

[0009] a buoyancy adjusting mechanism connected with the buoyancy mechanism, for adjusting the additional buoyancy of the buoyancy mechanism, so that the water module maintains horizontal floating.

[0010] In one embodiment, the bearing frame is detachably connected with the water module.

[0011] In one embodiment, the buoyancy mechanism comprises a plurality of inflatable air bags.

[0012] The buoyancy adjusting mechanism adjusts the additional buoyancy by inflating or deflating the inflatable air bags.

[0013] In one embodiment, the buoyancy adjusting mechanism comprises:

[0014] a gas source;

[0015] a pipeline connecting the gas source and the inflatable air bags, the pipeline being provided with a valve;

[0016] a control module in communication with the valve, the valve being controlled to adjust the additional buoyancy.

[0017] In one embodiment, the load-bearing frame is configured as a truss structure, the truss structure comprising:

[0018] a plurality of rod members; and

[0019] a plurality of splicing connectors for detachably connecting two rod members;

[0020] wherein the plurality of rod members and the plurality of splicing connectors enclose a plurality of placement cavities for placing the buoyancy mechanism.

[0021] In one embodiment, the underwater module further comprises a fixing member, the buoyancy mechanism being fixed to the load-bearing frame by the fixing member.

[0022] The fixing member comprises a strap.

[0023] Embodiments of the second aspect of the present application propose a method for assembling an irregular underwater platform on water, comprising:

[0024] splitting the irregular underwater platform into a plurality of underwater modules;

[0025] transporting the plurality of underwater modules to a predetermined assembling sea area by a transport carrier;

[0026] sinking the transport carrier to detach the underwater modules from the transport carrier;

[0027] transferring all the underwater modules to an assembling carrier;

[0028] completing the assembling of the underwater modules on water;

[0029] The method further comprises connecting the waterborne balancing float of any one of the above embodiments to part of the water modules before all the water modules are transferred to the folding carrier and / or before the folding of the water modules on water is completed, and the buoyancy adjusting mechanism adjusts the additional buoyancy of the buoyancy mechanism to keep the water modules horizontally floating.

[0030] In one of the embodiments, the irregular water platform is configured as a four-column floating wind power semi-submersible platform.

[0031] The four-column floating wind power semi-submersible platform is divided into a first module and a second module.

[0032] The second module is an irregular module, and the waterborne balancing float of the water module is connected to the second module.

[0033] In one of the embodiments, the transferring of all the water modules to the folding carrier comprises:

[0034] The waterborne balancing float of the water module is connected to part of the water modules.

[0035] The water modules are transferred from the transport carrier to the folding carrier by using the wet tow equipment, and the water modules are kept horizontally floating during the transferring.

[0036] In one of the embodiments, the folding carrier is configured as a semi-submersible barge or a semi-submersible transport ship.

[0037] According to the waterborne balancing float of the water module and the waterborne folding balancing method, the bearing frame is firmly connected to the target water module on one side and bears and fixes the buoyancy mechanism on the other side, thereby providing an installation base for the entire device. The buoyancy mechanism is installed on the bearing frame and supplements additional upward lifting force for the water module by the buoyancy generated by itself, thereby offsetting the sinking or tilting trend of the module due to the irregular shape and the offset of the center of gravity. The buoyancy adjusting mechanism can actively adjust the additional buoyancy generated by the buoyancy mechanism, offset the center of gravity of the water module by dynamic adjustment, and finally keep the module horizontally floating. The water module leveling does not need to rely on the self-ballast system or external lifting equipment, but can realize the horizontal floating only by the waterborne balancing float of the water module, thereby reducing the dependence on large equipment and special facilities and reducing the operation cost.

[0069] Referring to Figure 1 , Figure 2 and Figure 3 At least one embodiment of the present application proposes a water module water balance buoy 100, which comprises a bearing frame 110, a buoyancy mechanism 120 and a buoyancy adjusting mechanism 130, the bearing frame 110 is used to connect with the water module 200; the buoyancy mechanism 120 is used to provide additional buoyancy and is arranged on the bearing frame 110; the buoyancy adjusting mechanism 130 is connected with the buoyancy mechanism 120 and is used to adjust the additional buoyancy of the buoyancy mechanism 120, so that the water module 200 remains horizontally floating.

[0070] According to the water module water balance float box 100 of the embodiment of the present application, the bearing frame 110 is firmly connected with the target water module 200 on one hand and bears and fixes the buoyancy mechanism 120 to provide a mounting base for the whole device. The buoyancy mechanism 120 is mounted on the bearing frame 110 and supplements additional upward lifting force for the water module 200 through the buoyancy generated by itself to offset the sinking or tilting trend of the module due to irregular shape and gravity center offset. The buoyancy adjusting mechanism 130 can actively adjust the additional buoyancy generated by the buoyancy mechanism 120, offset the gravity center offset of the water module 200 through dynamic adjustment, and finally make the module stably keep horizontal floating. The water module 200 does not need to rely on its own ballast system or external lifting equipment to achieve horizontal floating, but only through the water module water balance float box 100, which reduces the dependence on large equipment and special facilities, reduces the operation cost, and solves the problem that irregular water module 200 cannot independently keep horizontal floating.

[0071] Referring to Figure 2 and Figure 4 In some embodiments, the bearing frame 110 is detachably connected with the water module 200 to flexibly adapt to different scenes and water modules 200. Specifically, the water module water balance float box 100 further comprises a detachable connection mechanism 140, the detachable connection mechanism 140 comprises a detachable flange 141 and a detachable bolt 142, the detachable flange 141 is respectively pre-installed on the water module 200 and the bearing frame 110, and the detachable bolt 142 connects the detachable flange 141. When it is needed to provide a balance buoyancy for a certain water module 200, the bearing frame 110 can be connected with the module; when the module completes horizontal floating, transfer or folding, the bearing frame 110 can be detached for reuse for other modules, improving the utilization rate of equipment.

[0072] Referring to Figure 3 and Figure 4 In some embodiments, the buoyancy mechanism 120 comprises a plurality of inflatable air bags 121; the buoyancy adjusting mechanism 130 adjusts the additional buoyancy by inflating or discharging gas in the inflatable air bags 121. Specifically, the inflatable air bags 121 are provided with an inflation port 122, through which the gas is inflated and discharged.

[0073] In some embodiments, the buoyancy adjusting mechanism 130 includes a gas source 131, a pipeline 132, and a control module 133. The pipeline 132 connects the gas source 131 and the inflatable air bag 121, and a valve 1321 is arranged on the pipeline 132. The control module 133 is in communication connection with the valve 1321, and the additional buoyancy is adjusted by controlling the valve 1321. Specifically, the gas source 131 can be configured as an air compressor. When the underwater module 200 is tilted, the control module 133 receives a signal of the module tilt, which can be an input instruction after manual observation or automatic detection by a sensor. The control module 133 sends an instruction to the valve 1321 of the corresponding pipeline 132 according to the tilt condition. When the module is adjusted to a horizontal state, the control module 133 sends a closing instruction to the valve 1321, and the gas stops entering and exiting, so that the buoyancy of the inflatable air bag 121 remains stable, and the underwater module 200 maintains the horizontal state. Through the buoyancy adjusting mechanism 130, the buoyancy can be accurately adjusted, the center of gravity of the module can be quickly offset, the module can be quickly adjusted to and maintained in a horizontal state, and the leveling accuracy is high and the response speed is fast.

[0074] Referring to Figure 4 、 Figure 5 and Figure 6 In some embodiments, the bearing frame 110 is configured as a truss structure, which includes a plurality of rod members 111 and a plurality of splicing connectors 112 for detachably connecting two rod members 111. The plurality of rod members 111 and the plurality of splicing connectors 112 enclose a plurality of placement cavities 101 for placing the buoyancy mechanism 120. The underwater balance float tank 100 adopts a detachable and spliced truss structure, the specifications of the rod members 111 and the size of the inflatable air bag 121 can be flexibly adjusted, and the irregular underwater module 200 of different sizes and shapes can be adapted.

[0075] In some embodiments, the pipe member can be selected as a steel pipe. In addition to the steel pipe, the rod member 111 can also be selected from aluminum alloy pipe, glass steel reinforced plastic pipe, and other lightweight high-strength materials, which are suitable for scenes with strict requirements on the self-weight of the float tank. In addition to the detachable flange 141 and the detachable bolt 142, the splicing connector 112 can also use quick buckles, pin shaft connections, and other methods to improve the splicing efficiency of the bearing frame 110, which is suitable for emergency operations or frequent disassembly and assembly scenes.

[0076] In some embodiments, the splicing connector 112 includes a plurality of splicing flanges 1121 and splicing bolts 1122. The splicing flanges 1121 are arranged on the rod members 111, and the splicing bolts 1122 connect the splicing flanges 1121. Specifically, before production or assembly, the splicing flanges 1121 are first fixed at the end of each rod member 111. When two rod members 111 need to be connected, the flange faces of the first rod member 111 and the second rod member 111 are precisely fitted, the holes on the two flanges are completely aligned, the splicing bolts 1122 can be smoothly inserted, the splicing bolts 1122 are inserted through the two aligned flange holes, and nuts are tightened at the other end of the splicing bolts 1122. The two splicing flanges 1121 are tightly pressed together by the fastening force of the splicing bolts 1122, and finally the stable connection of the two rod members 111 is realized. When the size of the bearing frame 110 needs to be adjusted or the frame needs to be disassembled, the two rod members 111 can be separated by simply unscrewing the bolts. The splicing flanges 1121 and the rod members 111 can be reused and adapted to different scenarios.

[0077] Referring to Figure 7 In some embodiments, the underwater module underwater balance float 100 further includes a fixing member 150, and the buoyancy mechanism 120 is fixed to the bearing frame 110 through the fixing member 150. The fixing member 150 includes a binding belt. The firm connection of the bearing frame 110 and the underwater module 200 and the stable fixation of the inflatable air bag 121 ensure the stability of the module during floating and transferring, providing a guarantee for precise folding.

[0078] In some embodiments, a plurality of binding belts are provided and crosswise fixed on the bearing frame 110. Specifically, a group of binding belts are first wound along the transverse direction of the bearing frame 110, crossing the inflatable air bag 121 and the frame rod member 111; another group of binding belts are then wound along the longitudinal direction, forming intersection points with the first group of binding belts, and finally forming a cross-shaped constraint structure in the placement cavity 101. The intersection points need to be aligned with the central area of the inflatable air bag 121 to ensure that the binding force of the binding belts acts uniformly on the surface of the inflatable air bag 121, avoiding local excessive stress leading to deformation of the inflatable air bag 121; the two ends of the binding belts need to be firmly fixed on the rod members 111 of the bearing frame 110, which can be locked by buckles, fastened by bolts, etc. The tightness of the binding belts can be adjusted to make the inflatable air bag 121 tightly fit the inner wall of the placement cavity 101 without loose gap. Further, if the size of the inflatable air bag 121 is larger, a plurality of groups of binding belts can be added on the basis of crosswise intersection, such as a "rice" shape, to further improve the fixing strength and cope with extreme conditions such as strong water flow and module inclination.

[0079] Compared with the single-directional binding fixation, the cross layout can form a three-dimensional constraint from the horizontal and vertical dimensions, which can not only avoid the sliding of the inflatable air bag 121 along the frame rod 111 under the impact of water flow, but also prevent the up-and-down movement of the inflatable air bag 121 due to the change of buoyancy and the inclination of the module, so as to ensure that the buoyancy mechanism 120 is always in the preset placement cavity 101 position and ensure the accuracy of the buoyancy point. The cross-bound binding can evenly disperse the weight, buoyancy and water flow impact force of the inflatable air bag 121 to the multiple rods 111 of the bearing frame 110, avoid the local binding force concentration leading to the damage of the inflatable air bag 121, and at the same time, reduce the load of a single binding and improve the overall durability of the fixing structure.

[0080] The underwater module underwater balance float 100 provided by the application selects the corresponding size of the pipe according to the size, shape and gravity center position of the irregular module, splices the pipe on site to form a bearing frame through the splicing connector 112, and fixes and connects the bearing frame 110 and the underwater module 200; the inflatable air bag 121 is installed in the bearing frame through the fixing piece 150 and connected with the buoyancy adjusting mechanism 130; the inflatable air bag 121 is inflated through the buoyancy adjusting mechanism 130, the amount of gas in the inflatable air bag 121 is adjusted according to the horizontal state of the underwater module 200, the buoyancy generated by the inflatable air bag 121 is used to offset the gravity center deviation of the module, and the underwater module 200 gradually reaches the horizontal floating state; if the underwater module 200 is inclined, the buoyancy distribution is adjusted by inflating or deflating the corresponding side inflatable air bag 121, and the underwater module 200 is maintained horizontally.

[0081] Referring to Figure 8 At least one embodiment of the application provides a water surface closing and balancing method, which comprises the following steps:

[0082] Step S100, the irregular underwater platform is divided into multiple underwater modules 200;

[0083] Step S200, the multiple underwater modules 200 are transported to a preset closing sea area by the transport carrier 300;

[0084] Step S300, the transport carrier 300 is sunk, so that the underwater modules 200 are separated from the transport carrier 300;

[0085] Step S400, all the underwater modules 200 are transferred to the closing carrier 500;

[0086] Step S500, the water surface closing of the underwater modules 200 is completed;

[0087] Before all the underwater modules 200 are transferred to the closing carrier 500 and / or before the water surface closing of the underwater modules 200 is completed, that is, before step S400 and / or before step S500, the method further comprises the following step:

[0088] The water module water balance buoy 100 in any of the above embodiments is connected to the partial water module 200, and the buoyancy adjusting mechanism 130 adjusts the additional buoyancy of the buoyancy adjusting mechanism 120 to keep the water module 200 horizontally floating.

[0089] Specifically, before all the water modules 200 are transferred to the folding carrier 500, i.e., before step S400, the water modules 200 are just separated from the transport carrier 300 and have not yet started to be transferred to the folding carrier 500. The purpose of the step of inserting the buoyancy and leveling is to first adjust the water modules 200 to a horizontally floating state by the buoyancy, and then perform wet towing transfer, so as to avoid uneven traction stress and water flow impact on the posture caused by the inclination of the water modules 200 during the transfer process, and ensure the stability of the transfer process.

[0090] Before the water folding of the water modules 200 is completed, i.e., before step S500, some or all of the water modules 200 have been transferred to the folding carrier 500, but the splicing and folding of the water modules 200 have not yet been completed. The purpose of the step of inserting the sub-buoyancy and leveling is to again calibrate the horizontal posture of the water modules 200 before splicing, so as to avoid the inclination of the water modules 200 caused by slight deviation during the transfer process, and ensure the accurate alignment of the splicing surfaces of different water modules 200, thereby providing conditions for subsequent folding.

[0091] According to the water folding balancing method of the embodiment of the present application, the five core links of splitting, transportation, floating and leveling, and transfer and folding of irregular modules are solved, the efficiency of loading and transportation is solved, the modular transportation of the floating body of the water module 200 is compared with the whole transportation, more goods can be assembled in a single voyage, and more transportation costs can be saved in ocean navigation; the module water unloading problem is solved, the water module 200 needs to be wet towed from the transport carrier 300 to the folding carrier 500 in a horizontal state, and in the case that the self ballast of the water module 200 cannot be adjusted, the module is horizontally ensured without the help of cranes and other equipment; through the water folding balancing method provided by the present application, a new idea is provided for the future water folding wet towing of irregular floating platforms.

[0092] Referring to Figure 9 , Figure 10 and Figure 11In some embodiments, the irregular underwater platform is configured as a four-column floating wind power semi-submersible platform; the four-column floating wind power semi-submersible platform is split into a first module 210 and a second module 220; the second module 220 is an irregular module, and the underwater module underwater balance buoy 100 is connected to the second module 220. The first module 210 includes three columns, which can maintain an underwater balance state by adjusting the ballast water itself, so as to unload the wet tow; the second module 220 is irregular in shape and has a high center of gravity, and after the auxiliary buoyancy of the underwater module underwater balance buoy 100 is increased, the second module 220 can maintain a balance state to unload the wet tow. The modular transportation of the four-column floating wind power semi-submersible platform and the on-water assembly scheme thereof can save a large amount of shipping cost.

[0093] Specifically, in some embodiments, an on-water assembly balancing method includes:

[0094] The transport carrier 300 is configured as a semi-submersible ship, and two semi-submersible ships respectively transport the first module 210 and the second module 220 of the four-column floating wind power semi-submersible platform to a predetermined assembly sea area;

[0095] Then the semi-submersible ship is sunk, the first module 210 is adjusted to be horizontal by adjusting the buoyancy ballast, and the first module 210 is wet towed away from the semi-submersible ship. For the second module 220, the underwater module underwater balance buoy 100 needs to be installed to increase the buoyancy of the second module 220, solve the eccentric problem, and finally make the second module 220 horizontally float and wet tow away from the semi-submersible ship.

[0096] Referring to Figure 11 In some embodiments, the on-water assembly balancing method further includes providing a temporary support mechanism 600, which is detachably installed on the underwater module 200, such as the first module 210 and / or the second module 220, for enhancing the rigidity of the first module 210 and / or the second module 220. In particular, the irregular second module 220 of the four-column floating wind power semi-submersible platform makes it maintain structural stability during transportation and assembly.

[0097] In some embodiments, step S400, transferring all underwater modules 200 to the assembly carrier 500, specifically includes:

[0098] Connecting the underwater module underwater balance buoy 100 to part of the underwater modules 200;

[0099] Using the wet tow equipment 400 to transfer the underwater modules 200 from the transport carrier 300 to the assembly carrier 500, and the underwater modules 200 maintain horizontal floating during the transfer process.

[0100] Through the above setting, the water module 200 always floats in the water, is not lifted out of the water surface, but is half immersed or fully floated in the water, the bottom is in contact with or close to the water surface, and relies on the buoyancy to support its own weight. By using the buoyancy of the water module 200 itself and the traction of the wet towing device 400, the module is moved on the water surface from the position of the transport carrier 300 to the designated area of the folding load.

[0101] Referring to Figure 11 and Figure 12 In some embodiments, the folding carrier 500 is configured as a semi-submersible barge or a semi-submersible transport ship. The semi-submersible barge can achieve a semi-submersible state by adjusting its ballast water, with most of the hull submerged in the water and the deck close to the water surface, so that the water module 200 transferred can be smoothly floated onto the deck, and then the hull is raised by adjusting the ballast to lift the module away from the water surface and fix it, facilitating subsequent splicing. The semi-submersible transport ship also has the function of semi-submersible adjustment, and has a large deck area and strong carrying capacity, and can accommodate multiple split water modules 200 at the same time, and after the transfer is completed, the modules can be spliced directly on the ship, reducing the step of secondary transfer of the modules and improving the operation efficiency.

[0102] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0103] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent application.
